Shards Server: 每个shard由一个或多个mongod进程组成,用于存储数据 Config Server: 用于存储集群的Metadata信息,包括每个Shar

集群由以下3个服务组成:

Shards Server: 每个shard由一个或多个mongod进程组成,用于存储数据
Config Server: 用于存储集群的Metadata信息,包括每个Shard的信息和chunks信息
Route Server: 用于提供路由服务,由Client连接,使整个Cluster看起来像单个DB服务器
另外,Chunks是指MongoDB中一段连续的数据块,默认大小是200M,一个Chunk位于其中一台Shard服务器上

下面,搭建一个Cluster,它由4台服务器组成,包括2个Shard,3个Config,,1个Route

其中每个Shard由一个Replica Set组成,每个Replica Set由2个Mongod节点,1个vote节点组成

搭建MongoDB集群

需要分别建立目录/opt/soft/mongodb/data/data ,/opt/soft/mongodb/log

192.168.11.229
/opt/soft/mongodb/bin/mongod –fork –shardsvr –port 10000 –replSet set1 –dbpath /opt/soft/mongodb/data/data –logpath /opt/soft/mongodb/log/log.log
/opt/soft/mongodb/bin/mongod –fork –shardsvr –port 10001 –replSet set2 –dbpath /opt/soft/mongodb/data/data1 –logpath /opt/soft/mongodb/log/log1.log
192.168.11.17
/usr/local/mongodb/bin/mongod –fork –shardsvr –port 10000 –replSet set1 –dbpath /opt/soft/mongodb/data/data –logpath /pvdata/mongodb_log/mongod.log
192.168.11.227
/usr/local/mongodb/bin/mongod –fork –shardsvr –port 10000 –replSet set2 –dbpath /opt/soft/mongodb/data/data –logpath /opt/soft/mongodb/log/mongod.log
/usr/local/mongodb/bin/mongod –fork –shardsvr –port 10001 –replSet set1 –dbpath /opt/soft/mongodb/data/data1 –logpath /opt/soft/mongodb/log/mongod1.log

192.168.11.228
/usr/local/mongodb/bin/mongod –fork –shardsvr –port 10000 –replSet set2 –dbpath /opt/soft/mongodb/data/data –logpath /opt/soft/mongodb/log/mongod.log

192.168.11.229上mongo –port 10000连接mongo

config = {_id: 'set1', members: [
{_id: 0, host: '192.168.11.229:10000'},
{_id: 1, host: '192.168.11.17:10000'},
{_id: 2, host: '192.168.11.227:10001', arbiterOnly: true}
]}
rs.initiate(config)
rs.status()

192.168.11.227上mongo –port 10000连接mongo
config = {_id: 'set2', members: [
{_id: 0, host: '192.168.11.227:10000'},
{_id: 1, host: '192.168.11.228:10000'},
{_id: 2, host: '192.168.11.229:10001', arbiterOnly: true}
]}
rs.initiate(config)
rs.status()

192.168.11.229:;192.168.11.17;192.168.11.228上启动进程
mongod --configsvr --fork --logpath /opt/soft/mongodb/log/config.log --logappend --dbpath /opt/soft/mongodb/data/configdata --port 20000

192.168.11.227上启动进程

mongos --fork --configdb "192.168.11.229:20000,192.168.11.17:20000,192.168.11.228:20000" --logpath /opt/soft/mongodb/log/mongos.log

192.168.11.227

mongos> use admin
mongos> db.adminCommand({ addShard : "set1/192.168.11229:10000,192.168.11.17:10000"})
mongos> db.adminCommand({ addShard :"set2/192.168.11.227:10000,192.168.11.228:10000"})
mongos> db.adminCommand({enablesharding:'test'})
mongos> db.adminCommand({listshards:1})
mongos> printShardingStatus()
mongos> db.adminCommand({shardcollection:'test.test2', key:{_id:1}, unique : true})

导入文本数据(数据以,号隔开)

mongoimport -h 192.168.11.227 -d test -c test --type csv -f ip,sid,uid,cateid,type --file /opt/dm/meta/uidip_20111017
